I'm gonna lose it over a PSU!!!

I'm venting here because you would all understand!

I Built a pretty good system-

Asus M2A-MVP MOBO
AMD AM2 6400+ 64x2 CPU
4 GB RRAM
ATI Saphire HD2600XT 512 Vid Card
Creative 7.1 sound
2- Lite on DVD Drive/burners
320gb WD HDD
Front Card reader
600W Roswell PSU

Its up and running for 7 days. Gets a 4.3 Rating on Vista and then ----Nothing.
Turn it on and the fans run, the drives light up as well as the card reader. It just does not POST.
I RMA the MoBo to Newegg and put the new one in and nothing. The HDD is dead!
Sooooo.....
I RMA the HDD to Newegg.
Get it all together and It works great.
2 Days later Turn it on and Nothing....No fans, no lights-DEAD!
Try a spare PSU and it turns on but will not POST. Fans run, drive lights work etc. Just won't POST.
I guess the PSU was bad in the begining!
So back to square one. I am RMAing the PSU to Newegg, MoBo to ASUS and the HDD...I will test that tommorow when I get home. It's been a great ride!

You're just full of static electricity and you don't know it!
Stop zapping those boards
Good to see someone has finally bought 600Watt though (450 just doesn't cut it)

have you bothered to check if your ram is compatible with the mobo book?
